Oseltamivir is used for influenza virus A and B infections.
Follow the dosing instructions carefully and remember to complete the course.
You can help prevent the virus from spreading to others by using clean tissues to cover your mouth and nose when you cough or sneeze, and by washing your hands regularly.
N'oubliez pas de rester au chaud, de boire beaucoup et de vous tenir à l'écart des foules.

About oseltamivir
Type de médicament | Un médicament antiviral |
Utilisé pour | Treating or preventing flu (influenza) |
Également appelé | Tamiflu®; Ebilfumin® |
Disponible en | Capsules and oral liquid medicine (suspension) |
Oseltamivir treats flu (influenza) by preventing the viruses causing the infection from spreading once they are inside your body. This reduces the symptoms of the influenza infection. It also reduces the risk of other problems which can sometimes occur alongside flu, such as pneumonia. It is most effective when it is started within an hour or two of the first symptoms of infection, but it can still be effective after this time, as long as it is started within 48 hours of the first symptoms.
Oseltamivir is also used to prevent flu when there are high numbers of people with influenza in the community, such as in epidemics and pandemics. It is used for those who have been in close contact with people with flu and for those who would be at particular risk if they developed flu (such as young children, people with long-term medical conditions, and the elderly).
Oseltamivir is not a substitute for seasonal flu vaccination.
Before taking oseltamivir
Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking oseltamivir it is important that your doctor knows:
If you are pregnant, trying for a baby or breastfeeding. Although you can take oseltamivir if you are expecting or feeding a baby, it is important that your doctor should know about this so that you can be made aware of the benefits and any risks of treatment.
If you have any problems with the way your kidneys work. This is because your dose may need adjusting.
Si vous prenez ou utilisez d'autres médicaments. Cela comprend tous les médicaments que vous prenez et qui sont disponibles sans ordonnance, ainsi que les médicaments à base de plantes et les médicaments complémentaires.
Si vous avez déjà eu une réaction allergique à un médicament.

How to take oseltamivir
Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about oseltamivir and it will provide you with a full list of side-effects which you may experience from taking it.
Oseltamivir should be taken exactly as your doctor tells you to. This is particularly important if you are giving oseltamivir to your child, as the dose prescribed will depend upon the age of your child. Younger children are likely to be prescribed a liquid medicine. Follow the dosing instructions on the pack carefully.
Oseltamivir is a course of treatment. It is important that you finish the whole course (even if you do not feel unwell); otherwise the infection could return.
If you have been prescribed oseltamivir because you already have flu symptoms, you will need to take one dose twice each day for at least five days. Start taking it as soon as possible and space the doses evenly throughout the day. So, for example, take one dose in the morning and the other in the evening.
If you are taking oseltamivir because you have been in contact with someone with flu but do not have any symptoms yourself then you will be prescribed one dose a day for at least ten days. Start taking the capsules (or medicine) as soon as you collect your prescription, and from then on, take one dose a day, preferably in the morning with breakfast.
Swallow oseltamivir capsules with a drink of water. You can take your doses either before or after meals, although taking the doses after food can often reduce the risk of feelings of queasiness.
Si vous oubliez de prendre une dose, prenez-la dès que vous vous en rendez compte (sauf s'il est presque temps de prendre la dose suivante, auquel cas ne prenez pas la dose oubliée). Ne prenez pas deux doses en même temps pour compenser une dose oubliée.
How to measure the correct amount of oseltamivir liquid medicine
(Note: your pharmacist will probably have prepared the medicine for you when you collect your prescription. If this has not been done and there is only powder in the bottle, you will need to add 55 ml of water. There is a measuring cup included in the pack, which has a line on it showing how much water to use. After you have added the water, shake the bottle well to mix the water with the powder. Then, push the bottle adapter into the neck of the bottle and replace the cap.)
Shake the bottle well and remove the cap.
Push down the plunger of the dispenser (oral syringe) as far as it will go (so that the plunger goes down to the tip).
Insert the tip of the dispenser into the adapter in the neck of the medicine bottle.
Turn the bottle with the dispenser attached, upside down.
Slowly pull out the plunger of the dispenser to fill it with medicine up to the mark which corresponds to the dose you need.
Turn the bottle with the dispenser attached, upright again.
Slowly remove the dispenser from the bottle.
Put the suspension directly into your (or your child's) mouth by pushing in the plunger of the dispenser. Swallow the medicine. You can eat or drink something after swallowing the medicine if you wish.
Take the dispenser apart and clean it by rinsing both parts under warm tap water.
Tirer le meilleur parti de votre traitement
The dispenser in the pack of liquid medicine measures doses up to 10 ml. If you have been given oseltamivir to give to child under 1 year of age, your doctor will give you a smaller dispenser to use which measures up to 3 ml.
Essayez d'empêcher la propagation de la grippe à d'autres personnes. Pour ce faire, n'oubliez pas d'utiliser des mouchoirs propres pour couvrir votre bouche et votre nez lorsque vous toussez ou éternuez, mettez les mouchoirs à la poubelle après usage et lavez-vous régulièrement les mains à l'eau chaude et au savon.
Remember to keep warm, drink plenty of fluids and stay away from crowds. If your symptoms do not improve or if they get worse, phone your doctor for further advice.
